Abstract

Abstract Offshore anthropogenic activities often produce high levels of noise below 1000 Hz, which can be serious threats to aquatic crustaceans based on the knowledge about their acoustic sensitive bandwidth. This study simulated noise with main frequency band similar to common underwater engineering noises, and examined its effects on movement behavior and physiological response, indicated by heat shock protein 70 (HSP70) gene expression, of the mud crab Scylla paramamosain. Experiments were conducted in the tanks, equipped with hydrophone, transducer, and video recording system, using juvenile S. paramamosain. Three acoustic stimulations with ascending levels were separately imposed on the animals. Results showed that the linear sweep with the sound power spectral density greater than 110 dB re 1μPa2/Hz in total bandwidth (100–1000 Hz), and 155 dB re 1μPa2/Hz within 600–800 Hz, could increase locomotor activities and HSP70 gene expression significantly.

声刺激下泥蟹血细胞运动行为及HSP70基因表达的变化

海洋人为活动经常产生低于1000 Hz的高水平噪声，根据对水生甲壳类动物声敏感带宽的了解，这些噪声可能对水生甲壳类动物构成严重威胁。本研究模拟了与常见水下工程噪声相似的主频段噪声，以热休克蛋白70 (HSP70)基因表达为指标，研究了噪声对泥蟹Scylla paramamosain运动行为和生理反应的影响。实验在装有水听器、换能器和录像系统的水箱中进行，实验材料为paramamosain幼鱼。分别对动物施加三种强度递增的声刺激。结果表明，总带宽(100 ~ 1000 Hz)声功率谱密度大于110 dB re 1μPa2/Hz, 600 ~ 800 Hz范围内声功率谱密度大于155 dB re 1μPa2/Hz的线性扫描可显著提高运动活动和HSP70基因表达。

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
